An implementation of nauty in Haskell (yes, I know about hgal, but it's slow and unmaintained). Work on this is halted until the generic graph classes are sorted out (and when I can pry some time out from hacking on graphviz, etc.).

2.2 Not quite code, but still...

I'm an unofficial developer in the Gentoo-Haskell team (which means I write a lot of ebuilds for it, but haven't bothered to make it official). My work on haskell-updater grew out of my frustration at having to manually rebuild packages.
